论文摘要
在本文中，我们研究了一个恒定的通货膨胀模型，该模型是由典型的标量场引起的，用于温暖通货膨胀的典型标量场，并具有恒定的耗散参数q = $γ$/3H。我们确定了与缩放器场运动方程相连的Friedman方程的分析解决方案。还使用修改后的langevin方程研究了原始标量和张量扰动的演变。为了检查模型的可行性，我们使用数值方法并绘制一些数字。我们对标量光谱指数和张量比比率的结果表现出与观测值良好的一致性。
In this article we study a constant-roll inflationary model in the context of brane-world cosmology caused by a quintessence scalar field for warm inflation with a constant dissipative parameter Q =$Γ$/3H. We determine the analytical solution for the Friedman equation coupled to the equation of motion of the scaler field. The evolution of the primordial scalar and tensor perturbations is also studied using the modified Langevin equation. To check the viability of the model we use numerical approaches and plot some figures. Our results for the scalar spectral index and the tensor to scaler ratio show good consistency with observations.
